I’ve been trying to find some work as a freelance writer, and wracking my brain trying to come up with an original name for my “business.” Most of the things I could think up using “write” were already being used by someone else. In desperation, I tried the Latin and Greek versions, and I think I finally found something:

Main Entry: grapho·ma·nia
Pronunciation: \,graf-ō-‘mā-nē-ə, -nyə\
Function: noun
: a compulsive urge to write
—grapho·ma·ni·ac \-nē-,ak\ noun

That sounds like me—compulsive urge to write.
